A Call For Help - Please, Stop the Attack(s)

Hello, for the record I am banned on r/ruby and r/rails and ruby-talk for what? Now I am under (ongoing) attack on github (and reddit) and on (for two weeks going). Does anyone care? (A rethoric question, isn’t it?) For the record - Please, rethink the perma-ban policy and actually ban perma-bans.
